| titleOfInvention | Fluorescent spectrum analysis method for detecting trace Zn＜2+＞ and F＜-＞ or AcO＜-＞ |
| abstract | The invention relates to a fluorescent spectrum analysis method for detecting trace Zn＜2+＞ and F＜-＞ or AcO＜-＞, belonging to the technical field of analytical chemistry. The method takes 1, 5-bi (7-hydroxy-8-coumarin-methylene)-disemicarbazide as a fluorescent reagent s3 and is used for detecting trace Zn＜2+＞ and F＜-＞ or AcO＜-＞ by a fluorescence method. In a DMF (N, N-dimethyl formamide)/H2O (2/ 3, v/v) solution, when Zn＜2+＞ is measured, the fluorescence excitation wavelength is determined as 360nm, the fluorescence intensity at the wavelength of 454nm is measured, the detected concentration linear range is expressed by two orders of magnitude, and the limit of detection is as low as 10＜-8＞mol* L＜-1＞; in the DMF solvent, when F＜-＞ or AcO＜-＞ is measured, the fluorescence excitation wavelength is determined as 400nm, the fluorescence intensity at the wavelength of 480nm is measured, the detected concentration linear range is expressed by two orders of magnitude, and the limit of detection is as low as 10＜-8＞mol* L＜-1＞. The reagent s3 is developed and synthesized by the inventor, and has the structural formula shown in the description. |
